Step 4: iPhone will prompt you that will delete all media and data, and reset all settings. Click Erase iPhone and it would be OK.

Few minutes later, all data and settings have been erased from iPhone. iPhone restarts and restore to factory settings.

Option 2: How to remove documents and data in iPhone

Documents and data are the data produced when you use programs in iPhone. Generally, “clear” option is available in every app for you to remove documents and data from iPhone. Open app information screen and you can clear cache data instantly. But it seems to be a little complex and troublesome. So I still look for other easy ways to remove iPhone documents and data at once.

For example, two other common ways below are used to remove data from iPhone apps.

Uninstall app and app documents and data would be removed from iPhone. Then if you want to use the app again, install it again on your iPhone.

Back up your apps, but not back up data with iTools, and uninstall apps in iPhone, then import the apps that have been backed up without backup data into iPhone.
